About me
I'm a backend engineer with around five years of commercial experience, built on Python and Django. Over the last two years I've gone deep into production AI — designing LLM pipelines, RAG search, and large-scale ETL that turn millions of raw documents into structured, queryable data.
Alongside the day job I designed, built, and shipped a monetized mobile app entirely on my own. So I'm as comfortable owning a product end to end as I am leading the technical direction of one inside a team. I care about clean architecture, real-world impact, and working with people who value growth and collaboration.
